Reconstruction of the Distal Oblique Bundle of the Interosseous Membrane: A Technique to Restore Distal Radioulnar Joint Stability.

The distal radioulnar ligament reconstruction is a technique that may be used for distal radioulnar joint instability without arthritis and failed nonsurgical management; clinical results demonstrate resolved or improved stability. Recent literature has focused on the distal oblique bundle of the interosseous membrane and its contributions to stability. This article describes a technically simple surgical technique to reconstruct the distal oblique bundle and restore distal radioulnar joint stability.

Distal oblique bundle reconstruction and distal radioulnar joint instability.

Background This study created an anatomic reconstruction of the distal oblique bundle (DOB) of the interosseous membrane to determine its effect on distal radioulnar joint (DRUJ) instability and compare this technique with distal radioulnar ligament (DRUL) reconstruction. Questions/Purposes We hypothesized that this reconstruction would provide equivalent stability to DRUL reconstruction and that combining the two techniques would enhance stability. Methods Six cadaveric upper limbs were affixed to a custom frame.

Open capsular shift and arthroscopic capsular plication for treatment of multidirectional instability.

Purpose: To compare the results of open inferior capsular shift with arthroscopic capsular plication for multidirectional instability in patients without a Bankart lesion. We hypothesized that there is no difference with regard to the specific clinical outcomes evaluated, including recurrent instability, range of motion, return to sport, and complications.

Methods: We conducted a comprehensive literature search.

Recurrent, locked posterior glenohumeral dislocation requiring hemiarthroplasty and posterior bone block with humeral head autograft.

This article describes the case of a 77-year-old man with a recurrent posterior shoulder dislocation, treated with humeral hemiarthroplasty and reconstruction of a large posteroinferior glenoid defect with a bone block created from humeral head autograft. On examination, the patient's left arm was held in internal rotation against his stomach, with minimal swelling about the deltoid. His shoulder was nontender to palpation; however, he had substantial motion restrictions, and attempted motion was painful.

Open reduction and internal fixation of clavicular nonunions with allograft bone substitute.

Background: Biologic augmentation with allograft has shown equivalent healing rates to autograft in several nonunion models. No literature exists clearly demonstrating this in the clavicle. The purpose of this study was to evaluate the healing and complication rates of clavicle nonunions treated solely with open reduction and internal fixation (ORIF) and allograft.
